Surface-enhanced Raman spectroscopy (SERS) has experienced an explosive resurgence in interest lately. Development of reproducible, spatially uniform SERS-active substrates has made this technique an attractive approach for identification of Raman-active compounds and biological materials including toxins, intact viruses, and intact bacterial cells–spores...

Hitachi introduces two new versions of the U-4100 UV-Vis-NIR Spectrophotometer: the Standard Solid Sample System and Large Solid Sample System. These new systems use PMT and InGaAs detectors, providing increased sensitivity in the range of 850–1700 nm. This results in reduced noise, making the instrument suitable for the measurement of low transmitting/reflecting anti-reflection coatings.

X-ray fluorescence spectroscopy (XRF) is one of the primary analytical tools used in the cement industry for a variety of related applications. The principle of XRF is relatively simple; a source directs X-rays onto the atoms of the sample, ejecting electrons from the inner electron shells.
